SUMMARY OF THE INVENTION

In view of the shortcomings of the conventional build-in closet hot water dispenser that is not safe for use and may cause water seepage, a vapor recovery and water collection box structure of a heating barrel of the present invention is achieved.

The primary object of the present invention is to provide a vapor recovery and water collection box structure of a heating barrel. The present invention comprises a vapor box, a heating barrel unit, and a faucet. The vapor box includes an upper box lid and a lower box tray. The upper box lid has a first guide opening, a second guide opening, and an air inlet. The first guide opening is fixedly connected with a backflow connecting tube. The second guide opening is fixedly connected with a check valve connecting tube. The air inlet is provided with a non-return air inlet valve. The upper box lid and the lower box tray are sealed against each other to form an accommodation chamber therebetween. The accommodation chamber is provided with a water collection trough and a float ball seat above the water collection trough. The float ball seat has a plurality of float ball limit grooves defined therein. A bottom side of each float ball limit groove is formed with a guide hole. An inner side of the guide hole is provided with a check ring. A float ball is provided above the check ring. The float ball is able to float and displace relative to the corresponding float ball limit groove. The heating barrel unit includes a barrel body. A top side of the barrel body is provided with a water inlet duct and a water outlet duct. The barrel body is provided with a heating controller disposed close to a bottom edge thereof. A side of the water inlet duct is provided with a recovered water guide mouth. The water inlet duct is provided with a water inlet tube extending into the barrel body close to the bottom of the barrel body. A side of the water outlet duct is provided with a vapor guide mouth. The faucet includes an outer tube and an inner tube in the outer tube. The vapor box is fixedly disposed on top of the heating barrel unit. The backflow connecting tube of the first guide opening of the vapor box is connected to the recovered water guide mouth of the water inlet duct of the heating barrel unit. The check valve connecting tube of the second guide opening is connected to the vapor guide mouth of the water outlet duct. The water outlet duct of the heating barrel unit is connected with the inner tube of the faucet. By the characteristic that the specific gravity of cold water is greater than that of hot water, when the cold water is guided from the water inlet duct into the barrel body of the heating barrel unit and heated by operating the heating controller, the hot water and vapor after heating are stored at the upper part of the barrel body. The vapor and condensed water are guided to the water collection trough and the accommodation chamber of the vapor box from the recovered water guide mouth of the water inlet duct via the backflow connecting tube. The vapor is guided from the check valve connecting tube of the second guide opening of the vapor box to the vapor guide mouth of the water outlet duct, and then guided out from the water outlet duct to the inner tube of the faucet, preventing the accumulation of the vapor from generating biogas. The check valve connecting tube only guides out the vapor and restrains backflow of the condensed water. The vapor is guided out from the inner tube of the faucet, preventing the outer tube from generating heat. When the cold water is guided from the water inlet duct into the barrel body of the heating barrel unit, the recovered water guide mouth of the water inlet duct generates siphonage, allowing the condensed water in the water collection trough and the accommodation chamber of the vapor box to be siphoned to the recovered water guide mouth of the water inlet duct and flow back into the barrel body of the heating barrel unit, preventing the waste of a water resource. After the condensed water of the water collection trough of the vapor box flows back, the float balls in the float ball seat descend relative to the float ball limit grooves, and the float balls abut against the check rings provided in the guide holes so that the vapor box is in a vacuum state to prevent the presence of air when the hot water is guided out from the water outlet duct, such that the hot water is in the form of a forward flow rather than a diffuse flow to prevent the user from being scalded. Besides, the water inlet duct and the water outlet duct are disposed on the top side of the barrel body of the heating barrel unit, preventing water seepage. The present invention is safe for use and able to prevent leaks.
